  1. FULL-TIME

    Millwall 0-3 Bristol City

    A good sound win for Bristol City, who will be away at Sheffield United or Plymouth in round five.

  2. FULL-TIME

    Barnsley 1-0 Norwich

    It is Barnsley's afternoon. Callum Style's neat turn and finish sees off Championship leaders Norwich. The Tykes march on in to round five, where Chelsea or Luton are the opponent.

  3. Swansea City 5-1 Nottingham Forest

    Two minutes left for Forest to suffer.

  4. Sheffield United 2-1 Plymouth Argyle

    Michael Brown
    Former Sheffield United midfielder on BBC Radio 5 Live

    The last 15 minutes have been really uncomfortable, and with the games coming up United didn't need this ending.

  5. Barnsley 1-0 Norwich

    Time is almost up at Oakwell. I think it is Barnsley's afternoon.

  6. West Ham 4-0 Doncaster

    Oh, there was a chance for Donny to at least take something away with them. A ball is chipped over the top for Fejiri Okenabirhie to run on to. He carries the ball into the box but with just young keeper Trott to beat he blazes his effort way over the bar.

  7. CLOSE!

    Sheffield United 2-1 Plymouth

    Plymouth have a free-kick, send everyone up!

    United flick it on, it comes to Byron Moore but it's a tight angle and he can only skid a shot over the bar.

    FOUR minutes added on.

  8. Brighton 2-1 Blackpool

    It is looking like Blackpool's FA Cup run is going to come to an end. The last few minutes have been all Brighton, but then Blackpool did equalise from nothing just before half time...

  9. Barnsley 1-0 Norwich

    Heading towards injury time at Oakwell. Norwich in last chance saloon. It's all hopeful punts forward, though.

    The board goes up... three minutes to go.

  10. Swansea City 5-1 Nottingham Forest

    Six goals in this game now. This from Matt Grimes in the first half is still the best of the lot.

    Any more to come?

  11. Stylish celebrations

    Millwall 0-3 Bristol City

    Check out the backflip...

  12. goal

    GOAL - Swansea City 5-1 Nottingham Forest

    Oliver Cooper (85 mins)

    It's brillaint work from Jamal Lowe on the left. He wins the ball back, cuts inside and has a shot blocked in the area.

    It falls for Oliver Cooper, who has come chasing up for the rebound. He squeezes it past the goalkeeper at the near post.

    It should be saved but he won't care. This is messy now.

  13. Sheffield United 2-1 Plymouth

    Into the final five minutes. Plymouth have given this a good go but United are looking to just manage this home.

  14. Swansea City 4-1 Nottingham Forest

    Rare chance for Forest but Miguel Guerrero can only head it wide from a far way out in the box.

    Liam Cullen is off. He heads straight down the tunnel for treatment, still being supported by medical staff.

  15. SUBSTITUTION

    West Ham 4-0 Doncaster

    Bit of an odd one. Nathan Trott is on to replace Fabianski in goal. No injury, just a chance for the young lad to make his debut.

    And another young player gets his first taste of first-team action, as defender Jamal Baptiste comes on for Fredericks.

  16. Sheffield United 2-1 Plymouth Argyle

    Michael Brown
    Former Sheffield United midfielder on BBC Radio 5 Live

    Great spell from Plymouth, they are moving Sheffield United around and forcing them back. They have a little bit of confidence now.

  17. Swansea City 4-1 Nottingham Forest

    Swansea's Liam Cullen is being helped off by two of the medical staff. He doesn't look in good shape.

    Change expected shortly.

  18. GREAT SAVE!

    Brighton 2-1 Blackpool

    Massive chance for Brighton to put this out of reach as Neal Maupay is unmarked as he meets a cross inside the area but he fires straight at Chris Maxwell. Should have done better.

  19. Barnsley 1-0 Norwich

    Norwich have seven minutes to save themselves at Oakwell. They've made all five subs - Vrancic and Buendia included - but the home side are holding firm.

  20. Brighton 2-1 Blackpool

    Into the final 10 minutes here and it is Brighton who are looking the most likely to score at the moment.

    Blackpool have fresh legs on, though, with Oliver Sarkic, Bez Lubala and Sullay Kaikai all on.

    Is there to be one more twist in this game?
